NWS Fort Worth, TX wrote its last area forecast discussion before the first event at Apr 13, 7:55 AM CST, 35 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE FORT WORTH TX 855 AM CDT MON APR 13 2015 .UPDATE... HAVE INCREASED POPS TO 60-80 PERCENT FROM THE METROPLEX NORTHWEST TO BOWIE THEN EAST TO PARIS AND ATHENS. URBAN AND STREAM FLOODING LIKELY IN SOME AREAS. THE AREA OF STORMS WILL SLOWLY WORK NORTHEASTWARD THIS MORNING WITH ADDITIONAL ACTIVITY EXPECTED THIS AFTERNOON. 75 && .AVIATION... /ISSUED 717 AM CDT MON APR 13 2015/ CONCERNS WITH THIS TAF PACKAGE ARE NUMEROUS. FIRST IS THUNDERSTORM TRENDS...SECOND IS CLOUD/VISIBILITY TRENDS AND THIRD IS WIND SHIFT TIMING. AS FAR AS CONVECTION GOES...MODERATE INSTABILITY AND INCREASING LARGE SCALE LIFT SUPPLIED BY THE APPROACHING UPPER LOW IN THE WEST WILL CONTINUE TO BRING SCATTERED SHOWERS AND STORMS. SINCE THERE IS NO MAJOR MESO SCALE FORCING FOR CONVECTION...WILL FOLLOW CURRENT RADAR TRENDS AND INCLUDE TEMPO GROUPS FOR THUNDER AT DFW...AFW AND FTW. WILL ONLY MENTION SHOWERS AT THE OTHER NORTH TEXAS TAF SITES. THERE SHOULD BE A LULL IN CONVECTION FROM MID MORNING THROUGH EARLY AFTERNOON WITH A DECREASING LOW LEVEL JET. ADDITIONAL SHOWERS AND THUNDERSTORMS SHOULD ARRIVE AT METROPLEX TAF SITES AROUND 21Z WITH THE ARRIVAL OF A SLOW MOVING COLD FRONT. STORMS SHOULD SLOWLY TRANSITION TO THE SOUTH WITH THE FRONT AND REACH WACO AROUND 23Z. BETWEEN 04 AND 06Z STORMS CHANCES WILL BE ON THE DECREASE AT ALL SITES. A NEAR SATURATED LAYER NEAR THE SURFACE WILL KEEP MOSTLY IFR CEILINGS IN PLACE THROUGH MID MORNING WITH TEMPORARY MVFR AND EVEN BRIEF VFR CONDITIONS. VISIBILITIES WILL ALSO OCCASIONALLY FALL BELOW 5 MILES. ALL CEILINGS SHOULD LIFT TO VFR BY EARLY AFTERNOON. HOWEVER...CEILINGS WILL FALL BELOW 3000 FT WITH THE PASSAGE OF THE FRONT AND REMAIN MVFR TO OCCASIONAL IFR OVERNIGHT THROUGH TUESDAY MORNING. A SOUTH TO SOUTHEAST WIND WILL PREVAIL THIS MORNING AT SPEEDS LESS THAN 12 KNOTS. THE COLD FRONT SHOULD REACH THE METROPLEX TAF SITES AROUND 21Z AND WACO ABOUT 23Z. THE WIND WILL TURN TO THE NORTHEAST/NORTH WITH THE PASSAGE OF THE FRONT AT SPEEDS BETWEEN 8 AND 13 KNOTS ALONG WITH A FEW HIGHER GUSTS. 79 && .PREV DISCUSSION... /ISSUED 345 AM CDT MON APR 13 2015/ ACTIVE WEATHER CONTINUES ACROSS THE CENTRAL PART OF THE CONUS EARLY THIS MORNING. THUNDERSTORMS CURRENTLY STRETCH FROM WISCONSIN TO THE RED RIVER ALONG A COLD FRONT. ADDITIONAL SHOWERS AND STORMS ARE OCCURRING ACROSS MUCH OF TEXAS IN THE WARM AND MOIST AIRMASS WELL SOUTH OF THE FRONT. THIS IS ASSOCIATED WITH AS UPPER LOW...WHICH CAN BE SEEN ON SATELLITE SPIRALING ACROSS WEST TEXAS. THE BRUNT OF THIS CONVECTION HAS BEEN IN THE FORM OF AN MCS MOVING EAST ACROSS SOUTH TEXAS. THE NORTHERN EXTENT OF THIS COMPLEX IS BEGINNING TO GRAZE MILAM COUNTY AND CONTAINS SOME GOOD REFLECTIVITY CORES. THE PRIMARY THREAT FROM THE STRONGER STORMS WOULD BE SOME SMALL HAIL AND CLOUD TO GROUND LIGHTNING...ALONG WITH BRIEF HEAVY RAIN. THIS LINE IS ALSO DEVELOPING FARTHER NORTH AS IT MOVES EAST...SO IT WILL LIKELY AFFECT THE SOUTHERN COUNTIES OF NORTH TEXAS WITH OCCASIONAL STRONG STORMS THROUGH MID MORNING. FORTUNATELY...THE OVERALL TREND HAS BEEN A VERY SLOW WEAKENING ONE. FARTHER NORTH...CONVECTION HAS REMAINED MORE SCATTERED IN NATURE. THESE SHOWERS AND STORMS ARE MOVING NORTH AT 20 MPH OR SO AND HAVE AFFECTED THE DALLAS FORT WORTH METROPLEX AND SURROUNDING AREAS OVER THE PAST FEW HOURS. THE COLD FRONT WILL PROVIDE FOCUS FOR ADDITIONAL SHOWERS AND THUNDERSTORMS TODAY AS IT PUSHES SOUTH INTO NORTH TEXAS. THE ATMOSPHERE MAY BE A LITTLE WORKED OVER FROM THE ONGOING ACTIVITY. HOWEVER...THE COMBINATION OF THE FRONT AND THE UPPER LOW TO OUR WEST SHOULD ALLOW FOR AT LEAST A CONTINUATION OF SCATTERED SHOWERS AND STORMS AREA-WIDE TODAY. THERE WILL BE A DECENT AMOUNT OF INSTABILITY ACROSS THE REGION TODAY WITH SURFACE BASED CAPE GENERALLY BETWEEN 1000 AND 2000 J/KG. THIS WILL ALLOW A FEW SEVERE STORMS...BUT THE LACK OF SHEAR SHOULD PRECLUDE THE OVERALL SEVERE THREAT. THE FRONT WILL BEGIN TO STALL OVER THE SOUTHERN COUNTIES OF NORTH TEXAS TONIGHT AS THE UPPER LOW WEAKENS AND MOVES OVERHEAD. THE WEAKENING UPPER LEVEL SYSTEM AND QUASI-STATIONARY FRONT SHOULD GENERATE ANOTHER ROUND OF CONVECTION OVERNIGHT...PROBABLY STARTING AROUND MIDNIGHT AGAIN AS A 25 KT LOW LEVEL JET DEVELOPS. CHANCES FOR SHOWERS AND STORMS WILL LINGER INTO TUESDAY...BUT FALL INTO THE SLIGHT CHANCE CATEGORY LATE TUESDAY AND WEDNESDAY AS THE UPPER LOW SHEARS OUT. THIS WILL AT LEAST PARTIALLY BE THE RESULT OF A STRONGER UPPER LEVEL LOW PRESSURE SYSTEM DROPPING SOUTH FROM THE NORTHWEST INTO THE 4-CORNERS REGION. GOOD ASCENT WILL BEGIN ACROSS NORTH TEXAS THURSDAY AS THE UPPER LOW SLOWLY MOVES EAST ACROSS NEW MEXICO. CHANCES FOR SHOWERS AND THUNDERSTORMS WILL LIKEWISE INCREASE AREA-WIDE THURSDAY. MULTIPLE DAYS OF SCATTERED CONVECTION ARE EXPECTED WITH THIS SYSTEM THURSDAY THROUGH SATURDAY AS THE SYSTEM MAKES SLOW PROGRESS EASTWARD ACROSS THE SOUTHERN PLAINS. GOOD LAPSE RATES ASSOCIATED WITH THE COLD AIR ALOFT WILL CREATE AN UNSTABLE ENVIRONMENT...ESPECIALLY DURING THE AFTERNOON HOURS AS SURFACE HEATING BECOMES MAXIMIZED. VERTICAL SHEAR VALUES WILL ALSO BE A LITTLE STRONGER WITH THIS SYSTEM...SO WE SHOULD EXPECT AT LEAST A LOW-END THREAT FOR SOME SEVERE WEATHER EACH DAY. PRECIPITATION CHANCES WILL END FROM WEST TO EAST SUNDAY AS THE UPPER LEVEL SYSTEM HEADS EAST FOR THE MS AND OH VALLEYS. 30 && .PRELIMINARY POINT TEMPS/POPS... DALLAS-FT.
